Bayhydur® eco 701-90

Technical Datasheet | Supplied by Covestro
Bayhydur® eco 701-90 by Covestro is a low odor, bio-based hardner for waterborne systems. Offers high chemical resistance. It contains 61% biomass content. It can be easily dispersed in the aqueous phase, even at low shear forces such as typically found in trade applications where manual mixing is required. It has good miscibility with both acrylic polyols as well as polyurethane dispersions. It can be used as a crosslinking partner for waterborne polyol binders and as a crosslinker for roughly pH-neutral waterborne polymer dispersions. Bayhydur® eco 7190 is designed for two-component waterborne coatings. It is compatible with organic solvents such as esters or ethers. It has a shelf life of 6 months.
